,WINDING APPARATUS.

Application filed October 3, 1924. Serial No. 741,380.

This invention relates to certain improvements 1n winding apparatus, and 1s here 11- lustrated in its adaptation to spinning jennies, altho it is applicable for use in connection with twisters, formers, layers, roviug frames, spinning frames, etc. in which the product, while being revolved around a common axis to give it its twist, is presented to the coil, cop or ball and wound thereon. v r

The apparatus illustrated is particularly adapted for winding twine, thread, yarn or rope, or the like, in cylindrical, conical or otherwise shaped coils, in such a manner that the ends of the coils will be self supporting and so that'the distance between any two successive turns of the twine etc. will be substantially the same, regardless of the diameter of the coil or ball. In order 2 to obtain a coil or ball of twine, of desired density and uniformity of winding, it has been customary in the use of spinning jennies' and other like apparatus to first wind the twine onbobbins with disks or heads at each end thereof to keep the loops of twine from coming coil or ball and subsequently the twine was delivered from the bobbinto another-winding mechanism for producing the desired coil or ball preferably of a character having self-supporting ends; 1

Certain of the advantages of this invention reside particularly in the elimination of the rewinding step and in the production.

:5 of an apparatus by means of which the desired twine sity of using headed bobbins or spools and permits the use of acollapsible or other type ofcore of pa-per, {wood or the like and j the omission of the bobbin admits in many casesthe winding of larger or more suitably shapedcoils or balls,thus eliminating much rewinding and dotting.

Other objects and advantages relate to the details of form, construction, arrangement and operation of the apparatus, all

as will more fully appear from the follow- "off the end of thev winding can be efiected directly'as the 0 is delivered from the spinning or twlstlng equipment, which desired winding twine, such as binderv shape of ball in which,

Further, the invention avoids the neces ing description, taken in connection with the accompanying drawings, in which The figure is a sectional view of the flyer of a spinning jenny combined with the winding device of this invention.

In order to specifically illustrate the construction and operation of this invention,

it has, as abovesuggested, been disclosed in connection with a'type of spinning-jenny commonly use for spinning hemp or sisal fibre, but it will be understood that this invention is in no way limited or restricted by the above illustrative disclosure.

-The operation of portions-of the appara- -tus disclosed is that ordinarily used and well known in connection with this type of spinning jenny. By meansof the constant rotative movement of the capstans 1, driven by the relative rotation which they receive by being bodily carried around on the fiyer head -2 and at the same time the incorporated gears 3- engaging pin ion 4. which by means-of the hollow shaft -5 is driven by a belt applied to pulley 6, the fibre 7 is drawn through theusual nipper. At the same time by means of the belt applied to pulley 9 and the concentric shaft 10, the fibre, is twisted in the nipper and appears in its twisted format the point 7.

From the nipper the twine passes through the hollow shaft 1- and over the sheaves 1l and 12 to the laying device .13'and onto the coil 4-. c

. The operation of the structure so farde scribed is well-known, The coil-winding cylinder 15 is axiallysupported by the removable shaft -16-'and is connected to the tubular shaft -17? for simultaneous rotation therewith in the usual manner, the tubular shaft +17- being mounted within and carried by the concentric sh aft10.

The well-known practice of universal winding for which the apparatus of this invention is adapted consists of winding the twine in a coil with comparatively large pitch or distance between each successive turn, and also advancing approximately the width of the twine each successive traverse of winding as illustrated by the coil 14-, thus producing an interlocking effect which makes the coil self-supporting and eliminates the necessity of the headed bobbin or spool. To produce thiseflect with each successive 5 around the capstans layer of twine on a coil which is constantly growing larger, it is evident that the laying device -13 must be moved laterally in front of the coil 1 and this traverse motion must always be proportional to the number of turns of the twine that are wound on the coil in a given increment of time.

In other words, regardless of the diameter of the coil, the laying device must be moved the same distance for each turn wound on the coil. However, since the twine is made at a constant rate of speed and delivered by the fifyer +8- at a constant rate of speed, the turns of the twine wound on the coil in a given increment of time must always be inversely proportional to the variable diameter of the coil during that interval, and therefore the traverse movement of the laying device 13 must be inversely proportional to the diameter of the coil as well. as directly proportional to the number of turns of the twine wound on the coil in the given increment of time.

The twine, imparts some of the rotative movement ofthe flyer -8- to the coil-winding cylinder 1,5 and the tubular shaft 17-, and this amount is equal to the constant rotative; speed of the flyer minus the number of turns of twine which have been wound, on the coil in the given increment of time.

In order to produce the type of winding desired and described heretofore, the traverse movement of the laying device must always be, proportional to the number of turns of twine woundon the coil in the given increment of time, regardless of the diameter of the coil.

For the purpose of producing the desired speed of traverse movement ofv the laying device 13 the gear 18 is mounted on the tubular shaft 17.-- and made to rotate therewith. Engaging with the gear 18 is pinion -19 which is carried by but free to rotate around the flyer arm 2l which inturnconnects and is carried by the revolving; flyer heads -2- and -20. It is evident that the rotative speed of the pinion 19- around itsown axis is proportional to the difference between the speed that it is bodily carried. around by the flyer heads 2jand -2 0- on the fiver arm 21 and the speed of the. engaging gear -18 since both. rotative movements are in the same direction.v These two speeds represent respectively the speed of, the flyer and the speed of the winding cylinder, and as stated above, the speed of the winding cylinder is variable but always equalto the speed of the fiyer minus the number of turns wound on theooilin the given increment of time, Therefore, the. ifferencebetween these two speeds or the rot'ative speed of the pinion 19- is proportional to the. number. of turns wound on the coilinany increment of time.

To illustrate this better, suppose we let R represent the rotative speed of the flyer or the speed that the pinion -19 is carried around bodily by the fiyer heads 2- and 20- on the flyer arm -21-. Also let represent the number of turns of twine wound on the coil in any increment of time. Then the rotative speed of the gear l8 will be proportional to F-VV. Therefore, the rotative speed of the pinion 19 will be proportional to F-(F-W which reduces to W.

.As stated before, the traverse movement ofthe laying device must be proportional totbe number of turns of twine wound on the coil in the given increment of time, or ii. and wehave proven above that the rotative speed of-the pinion -19 is proportional to IV. Therefore, by selecting the proper ratio between the gear -18- and the pinion -'l9 to accon'ipany the pitch of the traverse screw 22 which is cut on the extended hub of the pinion lO any desired pitch of winding the twine on the coil -1-i can be accomplished by causing: the traverse forl; 23- carried in the hub of the laying device 13 to engage the thread of the double traverse screw 22-. In other words, the laying device -13- is carried back and forth in front of the coil --14: by the action. of the traverse screw 22- engaging the traverse fork -23- and since the screw rotates at a speed proportional to the number of turns of twine wound on the coil in the given increment of. time regardless of'the diameter of the coil, the laying device likewise will pass back and'forth in front of the coil at a speed always proportional to the number of turns wound on the coil in the given increment of time. This produces the desired type of winding known as universal winding and described heretofore.

In order to provide sufficient tension in the twine so that it willbe wound in a hard, smooth coil, suitable means should be provided for resisting the rotary movement of the shaft 17 which is driven by the twine through the coil-winding cylinder l5..

To accomplish this, pulley 24- may be mounted on the end of and made to rotate with shaft 17. The braking effect may be accomplished in any suitable way such as applying friction (irectly to the pulley 24. or what is more common, belting it to a differential friction device which it is not necessary to describe since it is used very extensively for spinningjennies of this type. and since ithas no bearing on the claims of this invention.

Altho I have shown a specific application of my invention to a particular machine, together with perhaps preferred details of form, construction or arrangement of the same, I do not desire to restrict myself to any particular application of the invention or arrangement of the same, except as the same may be specifically required by the claims hereto appended.
